Kamila and Sreejith’s 37-page review on the feasibility and importance of non enzymatic metabolic reactions for the origin of life has appeared in Chemical Reviews. We hope it will inspire others to pursue this direction. Congrats!

Our fourth experimental paper on the chemical origins of life is published in Nature Ecology & Evolution. It is the result of an international collaboration with researchers in Germany and Japan. We show that three common iron-based minerals promote the hydrogenation of carbon dioxide to give, almost exclusively, the intermediates and end-products of the Acetyl CoA pathway. This enzyme-free chemistry maps closely onto the biological pathway, suggesting it had geochemical origins. Congrats to Kamila and Sreejith from our group and thanks to our great collaborators!

Our third paper on the chemical origins of life is published in Nature. We show that ferrous iron promotes a one-pot reaction network that resembles the Krebs cycle and amino acid synthesis, starting from just pyruvate and glyoxylate. These enzyme-free reactions could have been a precursor to biological metabolism. Congrats to Kamila and Sreejith! Free read-only version here. Paywall version here.
